This invention appertains to a wheel iiange lubricator for railroadrolling stock of the type shown in the Ross et al. application forpatent, Serial Number 39,414, led July 19, 1948, now matured into PatentNo. 2,550,865 on May 1, 1951.

One of the primary objects of the present invention is the provision ofa novel driving connection between the pumps carried by the reservoirbody and the driving arm welded to the journal box, so that the drivingconnection can be accurately set and'adjusted relative to the positionof the reservoir body on the truck, and the position of the driving armon the journal box, to effectively take care of Variations in journalbox and truck frame conditions, whereby to bring about the desiredsmooth operation of the pumps by the sprung and unsprung parts of thetruck during the travel of a locomotive or other piece of railroadrolling stock.

Another salient object of the invention is to provide novel means forindependently adjusting the working stroke of each pump piston, so thateach pump in the reservoir body can be set to deliver the exact desiredquantity of oil needed for the particular wheel being served by thepump.

A further important object of the invention is the provision of meansfor simplifying the arrangement of the pumps in the reservoir and themounting thereof in the reservoir, so that the pumps can be easilyrepaired or cleaned when necessary.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specically described and claimed, and illustrated inthe accompanying drawings, in which drawings,

Figure 1 is a side elevational View of a railroad locomotive or car,illustrating one truck thereof and showing the improved ange lubricatoroperatively connected therewith.

Figure 2 is an enlarged detail vertical sectional view through the oilreservoir and one pump, the section being taken substantially on theline 2-2 of Figure 3, looking in the direction of the arrows.

Figure 3 is a fragmentary top plan view illustrating the mounting of thereservoir and the driving arm on the truck, parts of the view beingshown in section.

Figure 4 is a -transverse sectional View through the reservoir taken onthe line -ll of Figure 2, looking in the direction of the arrows.

Figure 5 is a fragmentary detail side elevational view of the upper endof the reservoir illustrating the adjusting arm for one of the pumps.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the letter L indicates generally, the improved lubricator for use withthe truck IB of a piece of railroad rolling stock, such a as locomotiveI I.

The truck I 0 is of the type found in general railroad use and hencewill not be described in detail, but the same includes the sprung frameI2 carrying pedestals I3, in which are slidably mounted for verticalmovement journal boxes I4 carrying the axles for the car wheels I5. Thejournal boxes I4 are carried by an unsprung part I6 of the truck.

The lubricator or oiler for the flanges of the car wheels l5, isautomatically operated by the movement between the sprung and unsprungparts of the truck I l), during movement of the locomotive or car andthe lubricator or oiler L is so yconstructed that the oil is forced upto the flange of the wheel instead of down by gravity. Hence, oil isonly supplied to the flanges of the car wheels while the car is inmotion.

The improved lubricator or oiler L, includes a reservoir body Il, theupper end of which is closed by a removable cover I8, rigidly held inplace by machine bolts I9. A gasket 20 can be interposed between thebody Il and the cover I3, to prevent loss of oil in the reservoir, andto prevent the entrance of dirt and water into the lubricator from theoutside. The reservoir body Il is provided at one lower corner with atransversely extending boss 2l formed with an opening 22 for a bearingbushing 23. The bushing receives a mounting bolt 24. One end of the boltis enlarged in diameter, as at 25, and this end is welded, as at 26, tothe sprung part I2 of the truck It, adjacent to one of the journal boxesI4. The outer end of the bolt has threaded therein a suitable lock nut2l, so as to retain the reservoir body on the bolt against displacement.Obviously, washers of the desired type can be placed between thereservoir body Il, and the sleeve 25, and the nut 2l' and the reservoirbody. The bottom wall 28 of the reservoir body can incline downwardlytoward one end to provide an oil sump, and a removable drain plug 29 canbe provided for the sump. Disposed within the reservoir body Il andcarried by the cover I8 are a pair of like pumps 3U and 3|. One pump isutilized for supplying oil to lubricate one car wheel and the other pumpis utilized to supply oil to another wheel. Under certain conditions,more oil may be required by one wheel than the other, and consequently,novel the sprung part cylinder block The bore 3A ycommunicates With thelower end of the` cylinder 33.v `Reciprocallyr mountedr within y .n thecylinder 33 is a pump plunger or piston 55,r

formed on a plunger' rod.: The pump plunger orpiston 35 rcan be providedwith a sealing ring, if suchy should be desired. A 'supporting `rod' 3Tf is securedto the: cover' i8., anddepends. therefrom,

and is-disposed between the cylinder blocks 52 ofthe pumps 3B and 3i.The supporting rod-is f rigidly'connectedgto the .cylinder blocks 32 bya suitable' bolt 33'.' Consequently; ,when theeoiver.

In orderk to bring about oscillation. 'of theistub shafts 39, I providean operating lever yoke de.

This yoke le includes spaced parallel arms er, which straddle thereservoir and a connecting bridge piece disposed at one end of thereservoir. The arms l5 carry split clamping rings il which receive theouter ends of the stub shafts 39. Bolts 5B are provided for tighteningthe split clamping rings il into gripping contact With the stub shafts39. When the stub shafts are independently turned for adjustment thebolts ll are loosened.

The lever yoke has formed thereon a socket de for detachably receiving aswivel ball formed on the end of a stud bolt 5|. The stud bolt in turnis rmly clamped to the lever arm 52. The lever arm 52 can be provided`with a series of openings for receiving the stud bolt 5l and the boltcan be placed in any selected opening. The end of the arm 52 from thestud bolt 5i is provided with a vertical eye 53 which receives a bearingpin 54 carried by the attaching arm or plate 55. The attaching arm orplate 55, is welded, as at 5B, or otherwise rigidly secured to thejournal box I4 which is adjacent to the reservoir body I1. To retain theswivel ball '55 in position, clamping plates 5l are rigidly secured tothe opposite sides of the socket 5U and resilient rings 58 can beinterposed between the clamping plates 5l and the ball 50. The use ofthe ball 50 forms an important feature of the invention.

In applying the lubricator to the truck l0 of'o. car, theattaching-sleeve 25 is Welded in place on l2 of the car truck lil,adjacent to a desired journal box, after which the arm or plate 55 isWelded to thejournal box. The active length of the lever armA 52 is hadby placingl the and this in'turn,

The cover itk can beprovided with a suitabley filler cap 55, anda screenG- can also be carried by the cover le inward rof the cap.l l

` Much stressis laid on the arrangement of the operating.yokel ed, and;its connection with the attaching armorplate55yas' desiredadjustments rcan be readily made during the installation of the lubricator on the cartruck. Likewise, the arrangement of the pumps and the operating stubshafts 35 therefor is also important.

The universal ball connection with the yoke 44 and the verticallydisposed pivotal connection between the attaching arm 55 and theoperating lever 52, allows movement in the connection between the yokeand the journal box to compensate for any shifting of the sprung andunsprung parts during travel of the locomotive. Thus, all strains areeliminated. It is to be noted, however, that the stud bolt 5i 'and theball 55 are bodily lifted up and down during the raising and lowering ofthe journal box, which bringsv about the rocking of the yoke 44. Thereservoir il is freeto roek on its bolt 24 to compensate for the arc ofmovement of the lever 52 and the yoke ell.

Changes in details may be made without departing from the spirit. or thescope of this invention, but What is claimed as new is:

l. In a flange oiler for car Wheels, an oil reservoir, means rockablyconnecting the oil reservoir to a sprung part of a car truck, a pump insaid reservoir including a cylinder and a pump plunger reciprocallymounted in the cylinder, an operating lever carried by the reservoir andoperatively connected to the pump plunger, an attaching plate rigidlysecured to an unsprung part of the car truck having a verticallydisposed pivot, an operating arm movable on said pivot, a ball headcarried by the operating arm for movement therewith, and a socket forsaid ball'head carried by the lever` 2. A flange oiler for car Wheels asset forth in The' borel 34 has 5 claim 1, and means for adjusting theball head longitudinally of the operating arm.
